Use M99 To Loop, Jump, and Return! - Haas Automation Tip of the Day
Вставка
- Опубліковано 5 жов 2024
- Nearly everyone has used an M99 in their CNC programs, but chances are, you didn't know that it has several different uses. That's right, not only does an M99 LOOP back to the beginning of your program, but it can also JUMP to another spot in your program, or RETURN back from a sub-program. Check out Mark’s latest video, where he explains how you can use an M99 command to LOOP, JUMP, or RETURN.

Didn't know the M99 "bump" M30 counter setting. Sweet! Learn something new every time man!
Jump command is cool. I always use Goto but that is a good option. I must say that M97 subs are one of my favorite things that the Haas control does
Great content and you do an excellent job of explaining how the codes work. This CNC programmer is grateful for your tip of the day videos.
the yellow fanuc book says if there are two n200 lines in a program, it is only and always the first n200 in program the m99 p200 jumps to. more trivia? glad you asked. the m99 pxxxx starts looking for its nxxxx from the very start of the program. back in the day with slightly slower controls, you could watch the program scroll as the nxxxx was searched for. fun times! especially on a one line led display!
p.s. this series of videos you do is both invaluable and brilliant. does haas offer you as an option to a new machine purchase?
Awesome.
Unnecessary I was using GOTO command.
Thanks, sir.
I’m gonna try that in fanuc control. 🙏
Excellent video as always! There is one little thing that I think is forgotten. M98 also has a L-function. This is very helpful on a lathe. When I am making a small batch of parts I simply put an M99 at the end of my program. Normally this would make my program loop unlimited times. But then In MDI modus I will call up my program with:
M98 P1234 L30
Where P is my program number and L the number of parts I want. There is a barpull function at the end of my program.
This way you don't have to mess with counters etc.
Yes! This is the most useful thing! However I'm guessing this will be covered in future videos about M97/M98. This video was just focused on the M99s role within these.
RicM4 - That “L” loop is great with M97, M98 subs. We’ll work it in to some future videos. Check out this older video on barpulling where we touch on it ua-cam.com/video/lFGSP9Mtzqg/v-deo.html. Thanks for the comment, well timed. - Mark, Haas Tip-of-the-day
Excellent point and I look forward to learning more about those soon!
Ha saw that NYC CNC feature on your page... been following him since he was in his apartment in NYC :-)
These videos are great! Thank you Mark and Haas :) I only knew of M99's use for subprograms and not the other 2 uses. I particularly like the ability to skip over code, that's AWESOME!
excellent video, can you program the number of times a cycle repeats?
Very useful thanks used this the next day
Классные станки HAAS , и работать на них одно удовольствие.
man i watch all the Haas videos. i don't even have a Haas machine :/
I watch them too , and many tips are applicable to other machines , besides the explanations are SO clear !!! Mark is an outstanding teacher.
I do some translation every month, it's really helpful.
I am very grateful for your channel and thank you for your amazing videos
What do you think is the best software for machining? And which one do you recommend?
Man you explain things well !!!
Perfect videos and tutorials as always.... Congratulations...
Excellent.. & please teach video for stop wearing insert in cnc lathe and insert technique
Tank you for your help
i've always used GOTO# never knew about using M99
Mark... put yourself in for a pay raise!
He sells more Haas machines than anybody else!
Sir, can you make a video on above macro programming turning as well. For OD grooving
explica bem demais!!
tendo um pouco de noção de inglês, ate consigo absolver bem todo ensino que esta dizendo!
Hello sir,
Urs videos are very good and easy to understand . Sir i want u should make a detail video of G10 code video for us
Ooooo! New format. Nice
Good Job Haas
Please could you please help me to calculate RPM and fees? End lathe
Tank you
Hello friend, what is the parameter number to disable the function that puts zero together with the letter example X inserting the command creates X0 only I would just like to insert the X.
Does it work in romote DNC mode?
Nice explanation
Do Haas machines understand/use GOTO? Does M99 offer an advantage over GOTO?
M99 offers the advantage of you don't have to have paid for the macro option to use it. GOTO requires macros, M99 doesn't.

Ah, thanks!
Use for lights out good for lights out and lamoine monitoring always got a fist bump on monday mourning when machine was still running worked great for profit sharing when based on how many hrs run just be sure hide m99 in middle of prg so as not noticed😊
So can an M99 P# go to a previous line, or does it only go to a later N#
Other words can you have
Program
N100
Program
Program
M99 P100
Program
M99 will jump to wherever that N-line is located in the program.
hello friends of haas. I wanted to know if there are videos of the G76 cycle already in my st-30 when I use it to restart at start instead of going up after each low pass. Thank you
Para hacer un salto incondicional me parece más claro utilizar GoTo
hello, could I ask for help in writing Gkod?
Genial aprendo cnc con ustedes y inglés también, denme trabajo para practicar:(
bro , u really awesome tq for m99 info
Yeah Mark if I want to skip code already complete I use M97 Pxxx If I am wrong contact me...MUCH SAFER
if you're not industry, the main issue with haas and all cnc is cost. for example if you were to take your mid 90s lamborghini diablo to the dealer for upgrades, maintenance, think you'd drop $22,775 ? I highly doubt it. And the diablo was a hell of a lot more than the $60K you paid for the haas.

If I want to run a program 2/3/4..... With example increment Z-30 axis how to do?
Go 91 z+30 becsure give G90absolutegoto absolute position then G91z-30. G90continue on i give zinctement in sub call withL= loops
Марк - лучший парень в Хаас! Верните его !!! С уважением из России!
Difference between geometry offset and work offset
Absolute and incremtal in america
Use with g41 tool dia offsett for regrind tool dia or to add or remove stock to work toward goal deminsion be sure to usa D=tool dia setting to fanuc or yasnac i remember use fanac offett use alot for thread milling used G91 z= pitch of thread pull
Also tip set T and H matching agrement on so as if edit wrong H# will not crash z axle this setting protect with errer flashing red light
Tool length offset make tip tool zero
thanks boss
Can it count sub cycle amounts
Absolutely add L in line of sub call that how i rough mill stock away and fast done so much chips ate hole thu augers had to put a liner in chip conveyer and weld steel around auger steel stiil eat out just had to buy new augers
Hi man, Haas machines uses iso or fanuc language?
Yasnac

Doesnt M99 return from local subprgm return to Nnn +1?
Dragongly fab - We have a video on M97 coming out this next week that will cover what you’re asking. In general, if an M99 is used as a subprogram Return, it brings
you back to the line just after the M97/M98/G65 that called it up. Stay tuned! - Mark, Haas Tip-of-the-day
Use G91 increment zup and G90 to work cords and G91 z back down back into G90 as used to mill stock down add L# loops from z level start at before sub all G91 z -# and ÷ by how much stock to remove like to make witness at level to mill down to and dykem up can call witness z zero and just scale how much stock to start milling z level and simply loop down was way used for years
How do i determine the loop amount?
FANUC command
Simple math
100/0 !!
CANT BELEIVE i WASTED SO MUCH TIME ADDING SLASHES
I will put larger and largish items that I want to jump at times in a subroutine with a Block Delete. That way there's only one /.
Explain about m98 with full details
M98 call out a sub outside of the main program but inside the memory. M97 calls a sub inside the main program. M98 works for most machines. M97 only works on Haas.
